As usual, manga dominates the chart of the Top 20 Adult Graphic Novels in the book channel, based on NPD BookScan data for December (12/2/18-12/29/18) provided to ICv2. The new volume of My Hero Academia, Vol. 16, tops the chart, and seven other volumes of the series also make the top 20. All the manga on the chart are from the publisher Viz, except for the most recent volume of the former manga powerhouse Attack on Titan.

The Adventure Zone, the gaming graphic novel that just won’t quit, is in second place. This book was released in July and has been in the top 20 every month since it came out.

Only two Big Two graphic novels make the top 20: DC’s Batman: White Knight, charting for the third month in a row, and Marvel’s Infinity Gauntlet.

Two older best-sellers reappear, perhaps getting a holiday boost from gift-givers: Am I There Yet? The Loop-de-Loop, Zigzagging Journey to Adulthood, by Instagram star Mari Andrew, and Everyone’s a Aliebn When Ur a Ablien Too, by Twitter personality Jomny Sun.

NPD BookScan collects weekly point-of-sale data on print books from over 16,000 locations including e-tailers, chains, mass merchandisers, independent bookstores, and more. NPD BookScan covers approximately 85% of the U.S. trade print book market. The ranks on this chart are based on piece sales. Some publishers classify titles that are primarily text, or art books, as graphic novels; we've removed those titles from the ranking above.
